" l BUILDING BLOCK.

Application filed January 24, 1923.

To @ZZ whom if may concern Be'y it known that I, ADoLPrr ANDERSON, a citizen of the United States, residing at Zumbrota, in the count-y of Goodhne and State of Minnesotr-i, have invented new and useful Improvements in Building Blocks, of which the following is a specification.

This invention relates to silo tiles or the like, and coinprehends a construction to provide for a strong' joint, and to increase the thickness and strength of the walls without materially adding to the weight of the tile, the walls being so designed as to form a better web to which the mortar will li ett'ectively adhered to.

The nature and advantages of the invention will be better understood when the following` detailed description is read in connection with the accompanying drawings,

the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure l is a. perspective view of a tile constructed in accordance with this invention.

Figure 2 is a View of a modilied form.

Figure 3 is a sectional View taken on the line 3-8 of Figure l.

In Figure l of the drawing, I have illustrated one form of the invention wherein it will be noted that the tile is formed with two cells l0, the latter being separated by a wall or partition 1l. This form of the invention distinguishes from the modified form illustrated in Figure 2, in that the modified construction is provided with but a single cell. Otherwise the both forms of the invention are constructed the same. It will thus be noted that the parallel sides of the tile have their inner faces formed with spaced projections l2, the projections affording the said sidesa configuration which increases the strength of the sides and in fact increases the strength of the tile in its entirety, but does not materially increase the weight of the tile. It is to be understood that the projections 12 can vary in shape and design without departing from the spirit of Serial No. 614,638.

the invention, and that the projections give to the sides an irregular surface which more eiiect-ively adheres to the mortar, and does not interfere with the drying process in the manufacture of the tile.

The upper end wall of the tile is provided with a groove.

construction of the silo and any other'struc` ture.

lVhile it is believed that from the foregoing description, the nature and advan.

tages of the invention will be readily apparent, I desire to have it understood that l do not limit myself to what is herein shown and described yand that such changes may be resorted to when desired as fallv within the scope of what is claimed.

Having thus describedt-he invention, I claim l. A hollow tile building block of elongated contour including spaced sides and end walls, transverse project-ions extending from the inner faces of the opposed side walls, and across the entire width thereof, said projections on each wall being equidistantly spaced apart, one end wall having a transverse depression, and projections extending from the outer side of the other end wall and arranged in right angular relation with respect to the projections in the side walls.

2. A hollow tile building` block of elongated contour including opposed parallel side and end walls, a transverse partition dividing the block into upper and lower halves, transverse projections extending inwardly from the opposed side walls, with the projections on each wall equi-distantly spaced apart, one end wall having a` transverse depression, and projections extending' from the outer side of the other end wall and arranged in right angular relation with respect to the projections on the side walls.

In testimony whereof l' affix my signatur ADoLPi-i i, ANDERSON.
